This invention relates to ventilators for 1 the windows of-closed automobile bodies, it particularly relating to a ventilator in the 4 form of an attachment which can be applied to the windows of, conventional forms of bodies. 7

One of the objects of this invention is to provide a ventilator so constructed and arranged as to be capable of being applied to the window of a closed automobile body without the aid of screws or similar fastening devices.

A furtherobject of this invention is to pro Vide a ventilator of the character described so constructed asto be adjustable as to width to enable the ventilator to be applied to automobile body windows'of different sizes.

Further objects of the invention will appear from the accompanying drawings, de- 2 scriptionand claims;

In the accompanying drawing: Fig. 1 is an elevation of the outer side of a portion of a window and its frame with my improved ventilator shown applied thereto. Fig. 2 is a section on the line A-A of Fig. 1.

Fig. 3 is a side elevation of a portion of a window frame of slightly modified form.

Fig. 4 is a side elevation of the same frame shown in Fig, 3 in connection with a portion of the window, with my ventilator shown applied thereto.

Fig. 5 is an enlarged section of a portion of the ventilator, the section being on the line CC of Fig. 1.

- Fig. 6 is a section on the line B--B of- Fig. 4.

Fig. 7 is a view of a portion of one of the sheet metalblanks from which the device is formed.

Referring to the drawings, 1 represents a metallic window frame of any suitable form, having an inner filler 2 of wood. The wooden fillers, are'grooved in the usual way indicated at 3 to receive the usual felt channels 5 in which the glass 5 of the window slides.

My improved ventilator is formed in two sections 6 and 7 of sheet metal which whenasi sembled are in overlapping relation. Each VENTILATOR FOB, AUTOMOBILE WINDOWS.

Application filed December 31, 1926. Serial no. 158,234.

section is formed of a sheet of metal having its outer end cut to the shape shown in- Fig. 7 and afterwards bent rearwardly on the line a to a substantially triangular form as indicated at 8 in Fig. 2. The upper edge of each section is bent on the dotted line I) of Fig. 7 at an obtuse angle to the main portion thereof to form a securing flange indicated at 9 and the rear edge of the triangular portion 8 is also bent on the dotted line 0 to form a continuation 9 of this flange 9. The lower edge of each section is also bent on the dotted line (1 as indicated at 10 to 'form a trough. In the construction shown in Figs. 1 and 2 each triangular section has secured to its lower edgenear the rear end thereof, a small .me-

tallic plate 11 which projects below the edge of the section 8 and is bent laterally and thence downwardly to form an angularly projecting lip 11'. In applying the ventilator,'

the two sections are separately secured to the window frame and then brought in overlapping relation with the overlapping parts secured together by short stove bolts 13, one of the sections, such as the one 7, being provided with slotted openings l i-and the other with round openings to receive the bolts so as to permit the two sections to b'e connected together in different positions. of adjustment. Each section is applied to the window frame by first inserting the lip 11' in an opening 15 drilled in the window frame and then slip- I ping the flange 9 and its extension 9' between the window frame and the felt channel as shown best inFig. 2 until the two sections are brought into proper overlapping relation to be secured by the bolts 13 before referred to; The overla ping portion of each section is preferably shown in Fig. 5. I

' In Figs. 3, 4 and5there is shown a frame of a character which precludes the employment of the lips 11 because of the fact that the inner edges of the frame are of peculiar form employin inwardly extending flanges 17. When suc a frame is encountered, an a ngularly extending slot 18 is sawedin the flange 17 and the lower edge of the triangularl -shaped portion 8 isslippedin this slot nt to form stiffening ribs 16 as 18, the lips 11 being discarded. As the ventilator section is turned to insert its edges in the glass channel in the manner before explained,the portion which has been inserted in the slot bends, as indicated ats8' in Fig. 4, to provide ineifect a lip which will have an engagement with the window frame and thus act the same as the lip 11' to prevent dislodgement of the Ventilator vertically after the parts have been fastened together.

In this arrangement, it will be seen that there is provided a window ventilator which may be applied .to the window frame-without the aid of such fastening devices as screws and the like. ,After the flanges 8 and 9 have been inserted between the frame and the felt channel, the lips 11, or 8, engaging the win dow frame, effectively prevent'the flanges 9 and 9' from slipping from their position be tween the frame and the felt channel, par

ticularly after the two parts of the ventilator have been joined together by the bolts. By forming the ventilator in two sections which may be adjustably connected together by the bolts, provision is nude for accommodating the ventilator to different widths of windows.

' The arrangement is one also which provides a v 'claim:
